How do you find area of an irragular shape if perimeter is given?
If given the total perimeter only it is impossible to do. However, if the lengths of each part of the perimeter are given (or can be worked out from the lengths given) then split the shape's area up into areas of shapes whose area you do know how to calculate, calculate each area and add them up. For example if you have a hexagonal L shape with lengths 1cm, 3cm, 3cm, 1cm, 4cm, 4cm, (all angles 90o) it can be split into two rectangular areas, one of 1cm x 3cm (from the top of the back of the L to the top of the piece across the bottom) and the other of 4cm x 1cm (all the way across the bottom of the L).
How do you do perimeter and area of L?
Area: Find some of the lengths, then cut the L in half and work it out from there. Perimeter: Add all the lengths together.
How do you calculate the area of a pyrmid?
Pyramid (regular) Lateral area : pl/2, where l = slant height : p = base perimeter Total area : pl/2+B where B = Base area.
How do you find the area of an irregular shape?
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
What is the perimeter of a square with an area of 144 in2?
Area = 144 sq inches => Length of side, L = 12 inches => Perimeter = 4*L = 48 inches.
How do you calculate the perimeter?
There are many shapes for calculating perimeter such as:Rectangle: 2(L+W) where L=length and W=weightSquare: 4s where s=# givenTriangle and most shapes: add up all the sidesCircle: 2∏r

How do you calculate a perimeter of a rectangular block?
perimeter of rectangle=2(l+b) l=length of the rectangle b=breadth of the rectangle
How do you calculate the perimeter of an area?
Add all sides of the area together to get the perimeter.Is the area is a Rectangle, then you can use the following formula:P = 2 L + 2 W(which means Perimeter equals two times the length plus two times the width)
How do you do perimeter and area of L?
Area: Find some of the lengths, then cut the L in half and work it out from there. Perimeter: Add all the lengths together.
What is area of square with perimeter 8?
as perimeter =8 so 4l=8 , so l=2. now area= [l][l]=(2)(2)=4
How do you calculate the area of a pyrmid?
Pyramid (regular) Lateral area : pl/2, where l = slant height : p = base perimeter Total area : pl/2+B where B = Base area.
What is the perimeter and area of a yard that length is 20ft and width is 15ft?
Perimeter l+l+w+w= 70ft Area LxW =300 sqft
Which of the squares has an area that is equal to its perimeter?
A square that measures 4 per side. Perimeter = L + L + L + L = 4L = 4*4 = 16 Area = L * L = 4*4 = 16 Although technically they won't be equal since perimeter has units of length, while area has units of squared length.
How do you find the area of an irregular shape?
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
How do you write a program to find the area and perimeter of a rectangle?
CLS PRINT "PROGRAM: Calculate both perimeter/area of rectangle" PRINT INPUT " Length"; length INPUT "Breadth"; breadth PRINT PRINT "Perimeter: "; 2 * (length + breadth) PRINT " Area: "; length * breadth END
How do you simplify an expression for the perimeter and area of a rectangle?
Represent the length of the rectangle by L and the width by W. The perimeter = 2L + 2W = 2(L + W). The area = L x W.
